Subwoofer:
In general, the use of a subwoofer is recommended. All subwoofers with a chassis of at
least 20 cm and minimum nominal output of 50 watts can be used. In the AV receiver set-
up, the cross-over frequency of all channels should be set to around 120 – 180 Hz or all
channels to "small" where possible. Please also observe the operating instructions for
your subwoofer and AV receiver.
GENERAL INFORMATION ABOUT CONNECTING YOUR MAGNAT LOUDSPEAKERS
Please always use a good quality loudspeaker connection cable from an audio dealer. To
prevent impairment of sound quality, we recommend cables with cross-sections of at
least 0.75 mm² for lengths up to 3 m and at least 1.0 mm² for lengths above 3 m.
Always turn off the amplifier or receiver before connecting or disconnecting loudspeaker
cables. Place the loudspeakers in their planned positions and cut the cables to the right
length. The cables for both channels should always be exactly the same length. Strip
10 – 15 mm of insulation from the ends of the cables and twist the ends. The loudspeaker
terminals are equipped with a clamping mechanism. Press the terminal head down and
guide the stripped cable end into the hole on the side. On releasing the terminal head, the
cable is secured, ensuring the best possible contact.
For good sound it is imperative that the cables must be connected in such a way that the
speakers are "in phase". This means that the black negative terminals on the speakers (-)
must be connected to the negative (-) terminals on the amplifier, the red positive (+)
speaker terminals to the positive (+) amplifier terminals. To make this easier one wire of
most speaker cables is marked with a coloured strip or a ridge in the insulation.
Before switching on the system double-check all your connections and make sure that the
terminal screws are tight and that there are no short circuits caused by stray wire
filaments – this could cause serious damage to your amplifier!
